Thanks for the tip! There is a slight rainbow effect, but the result is not bad. The best result I got was when increasing red and green together, alternatively with blue, with a blue component always a bit higher than the others. This give a nice result for the snow. You should see the result...

I was talking about 8-bit palettized mode. Each color of the palette is defined with 3 bytes, 1 byte for each component. However, if you set up a palette of 256 greys and you displays all of them on the screen, you see only 64 different greys on the screen (which makes impossible to display a...

OK, thanks for this information. Actually, it seems to be 18 bits, and not 16, allowing 262000 colors and 64 greys.

OK, Thanks for the link, which makes things a bit clearer. However, this does not explain why in palettized 8-bit mode, colors cannot be chosen from a 24-bit palette, but only from a 16-bit palette. It is quite surprising. Even my 15 years old A1200 can do that. Anyone can confirm that this is...

Hello! I am currently writing an homebrew game in which I render a snowy terrain. It needs grey scale, from light grey to white. Problem: the difference between two consecutive grey is quite big, much bigger than when I run the same program on my computer, so the result is not so nice. Do I...

Unlikely. Amiga is quite hard to emulate, the A500 emulation does not even run that good on the GP2X, and the 1200 is much more powerfull than the 500. UAE succesfully emulates A1200, but I thinks it needs a decent PC to run fullspeed. Obviously, I am talking about _real_ CD32/A1200 games. For...

Yesterday evening I tried to reproduce the bug and it happened to me, too. I even had a look at the code to check whether something was wrong. I found nothing. Then today I tried with other emulators, and the same thing happened. I think (if we are talking about the same thing) that it is an...

I have compiled it, but I did not solve the problem so far. If you want to have a look, the GP2X joystick management is not in usbjoy, but directly in emumain.c. If you find it, I will compile it for you. Good luck!

I already noticed that there were something wrong with the joystick, but I just believed I was killing my joystick playing 1944... I am going to have a look at the sources, but did you try to contact the coder?

You just have to get use to it! After some training, you can type way faster than with standard virtual keyboard. I think the keyboard managment in ZX-81's emulator is really great (I only tried Thom, but I guess it is similar for all of them), I especially like the fact that you can make...

Thank you so much ZX-81! Virtually all 25-35 years old people in France started computing on these machines, at school... So nice to have it on GP2X today. The most well-known programs on this computer were LOGO, the turtle programming language, and some not-so-fascinating educationnal...

Yes, the TO7-70 emulator would be great, that would remind me school time! And again, thanks to ZX-81 for Mancala (I am still looking for a right strategy...), and also for GNUGo2x, that would not exist without him!

Hello, My friend ZX-81, who is a PSP guru and will soon be a gp2x guru, can't post on gp32x.de. It's a pity. This post is: 1) A testing post, to check that I can post (sorry) 2) A welcome message for ZX-81 !!!

Hello everyone! A new version of GNUGo2X, my GNUGo GP2X port, is available here New features: - Save/Load SGF files - Improved graphics (thanks to Saehn) - Improved controls - CPU freq management (60 MHz when idle, 200 to 300 MHz when thinking) Please check online help, controls have...

sehs33: Yes, I do. yod4z: Thanks for the tip. I am going to have a look at it.

Hi, I need a simple file requester for my GnuGO2X project and I don't want to recode that from scratch. Do you have some experience with file requester in GP2X projects? Do you know a lib which would help, or an open-source project containing a file requester which could be easily integrated in...

Hi everyone, I have ported GnuGO and its PSP frontend PSPGGO to GP2X. From those who don't know, GO is a strategic board game coming from ancient china. More details here: http://en.wikipedia.org/wiki/Go_(board_game) Options available: - Game against GP2X or against another human player. -...

The biker is strictly speaking not in 3d. It is a (small) set of textured polygons that rotate. Furthermore, there is a -ugly option which removes all fancy opengl effects. It looks like a very good candidate for gpu940.
